cooling CHEVROLET MONTE CARLO 2005 6.G Owners Manual

Before your vehicle was shipped from the factory, it was
programmed to Mode 4. The mode to which the
vehicle was programmed may have been changed since
it left the factory. To determine the mode to which
your vehicle is programmed or to program your vehicle
to a different mode, seeVehicle Personalization on
page 2-38.
Disconnecting the vehicle’s battery for up to a year will
not change any previously programmed modes.
Lockout Protection
To protect you from locking your key in the vehicle, this
feature stops the power door locks from locking while
the key is in the ignition and a door is open.
If a power lock switch is pressed while a door is open
and the key is in the ignition, both doors will lock
and then the driver’s door will unlock. A chime will sound
continuously until both doors are closed.
Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-26.

Climate Controls
Dual Climate Control System
With this system you can control the heating, cooling,
defrost, defog and ventilation for your vehicle.
Manual Operation
Turn the right knob clockwise or counterclockwise to
direct the airow inside of your vehicle.
To change the current mode, select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode allows for approximately a
50/50 split of air to the instrument panel outlets and
to the oor outlets.
6(Floor):This mode directs most of the air to the
oor outlets, with some of the air directed to the
windshield and side window outlets. In this mode, the
system will automatically select Outside Air.
The right knob can also be used to select defog or
defrost mode. For more information, see “Defogging and
Defrosting” later in this section.
By positioning the right knob between two modes, a
combination of those two modes is selected.
It should be noted, that the air conditioning compressor
will be engaged unless the outside temperature is
40°F (4°C) or below. Recirculation cannot be selected
when in Floor Mode.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
If the airow seems low when the fan is at the highest
setting, the passenger compartment air lter, if
equipped, may need to be replaced. For more
information, seePassenger Compartment Air Filter on
page 3-25andScheduled Maintenance on page 6-4.

Engine Coolant Temperature GageThis gage shows the engine coolant temperature.
It also provides an indicator of how hard your vehicle is
working. During the majority of the operation, the
gage will read 210°F (100°C) or less.
If you are pulling a load or going up hills, it is normal for
the temperature to uctuate and approach the 250°F
(122°C) mark. When the gage reads greater than 250°F
(122°C), the HOT COOLANT TEMP light will be
illuminated in the message center and a chime will
sound continuously. If the gage reaches the 260°F
(125°C) mark, it indicates that the cooling system is
working beyond its capacity.

Battery Warning Message
When the vehicle is
started this message will be
displayed for
three seconds.
If the message is displayed when the engine is running,
you may have a problem with your charging system.
If there is a problem with the charging system,
four chimes will sound when the message comes on.
The battery display will also stay on while the key
is in ON until the engine is started.
If the message stays on after starting the engine it could
indicate a problem with the generator drive belt, or
some other charging system problem. Have it checked
right away. Driving with this message on could drain
your battery.
If you must drive a short distance with this message
displayed, it helps to turn off all your accessories.
Hot Coolant Temperature Warning
Message
This message is displayed when the cooling
system temperature gets hot. A chime will sound
continuously, also.
Check the coolant temperature gage and the coolant
level. SeeEngine Coolant on page 5-28,Engine Coolant
Temperature Gage on page 3-36andEngine
Overheating on page 5-31for further information.

If you drive regularly in steep country, or if you are
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
Keep your vehicle in good shape. Check all uid
levels and also the brakes, tires, cooling system,
and transaxle. These parts can work hard on
mountain roads.
Know how to go down hills. The most important
thing to know is this: let your engine do some of
the slowing down. Shift to a lower gear when you go
down a steep or long hill.
{CAUTION:
If you do not shift down, your brakes could get
so hot that they would not work well. You
would then have poor braking or even none
going down a hill. You could crash. Shift down
to let your engine assist your brakes on a
steep downhill slope.
{CAUTION:
Coasting downhill in NEUTRAL (N) or with the
ignition off is dangerous. Your brakes will have
to do all the work of slowing down. They could
get so hot that they would not work well. You
would then have poor braking or even none
going down a hill. You could crash. Always have
your engine running and your vehicle in gear
when you go downhill.
4-24

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
start your engine,
shift into a gear, and
release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle uid (don’t overll),
engine oil, drive belts, cooling system and brake system.
Each of these is covered in this manual, and the Index
will help you nd them quickly. If you’re trailering, it’s a
good idea to review this information before you start
your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating on
page 5-31.
